So you are bitching about Zoro being connected to Ryuma, even tough there was 100% chance he was from wano and looked like just like Ryuma that was designed before one piece even began.
I will only answer about that part because the rest about Sanji is clearly wrong on many levels.
Yeah Zoro coming from Wano was extremely likely. And frankly it wouldn’t really be a problem for me.
I would have obviously préfèred if Zoro was a complete nobody but why not. Like for Sanji, if Zoro « only » came from Wano and was the distant descendant of a daimyo I wouldn’t rant much.
And yes in Monster Ryuma looked a bit like Zoro.
But it was not carved into stone yet.
Here Oda went full bloodline and parallels : do you really like that Zoro has the exact same eye scar than Ryuma ? Do you really like that the two strongest swordsmen in history are related to each other by blood ? Zoro wants to be the strongest swordsman and conveniently his ancestor was the former one….
I have a problem with that
